背棘 (總數) : 0; 背的軟條 (總數) : 8 - 9; 臀棘: 0; 臀鰭軟條: 19 - 20; 脊椎骨: 38 - 40. It is characterized by the combination of the absence of a supraorbital bone, and the presence of a deep-lying midlateral stripe extending along the body onto the caudal peduncle, a band of chromatophores above the anal fin, and a small pair of inner row symphyseal teeth on the dentary (Ref. 59215). It has also an elevated vertebral count of 38 to 40, and 4 to 6 outer row premaxillary teeth are present with a majority of the specimens, with only 4 outer row teeth implanted in an alternating pattern with respect to the anterior inner row premaxillary teeth (Ref. 59215). Number of dorsal fin rays is ii,6-7 and anal fin rays is iii,16-17 (Ref. 59215). In life a broad, blue-green iridescent midlateral band covers the lateral flanks and tail from behind the opercle to the base of the caudal fin; this band overlies and obscures the deep lying midlateral stripe evident in preserved specimens; above and below the midlateral band the body is silvery white (Ref. 59215). Numerous melanophores are present on the head and opercle, and scattered over the body with a concentration around lateral scale margins (Ref. 59215). Dorsal fin and pectoral fins are dusky gray; adipose fin is pale grey with a dark distal margin; caudal fin is dusky gray and medially each fin fork is deep crimson red; anterior and distal margins of anal fin are white, while the remainder of the fin is jet black; pelvic fins are white (Ref. 59215). Body shape (shape guide): fusiform / normal. 它是特徵為組合那缺乏一個上眼窩骨, 與那有一深的-橫臥的延伸側面中央的斑紋在尾梗 , 在臀鰭上面的一條色素胞的條紋之上沿著身體, 與小的成對內部的列合生的牙齒在齒骨.(參考文獻 59215) 也它有 38 到 40 的升高脊椎骨數, 與 4 到 6 外部的列上頜骨前的齒出現具有一個標本的多數, 只有在一個交互的圖案被深植的 4個外部的列齒相對於前面的內部列上頜骨前的齒.(參考文獻 59215) 背鰭鰭條的數字是 ii, 6-7 ，而且臀鰭棘條是 iii,16-17.(參考文獻 59215) 一條寬的, 藍綠色彩虹色的側面中央的條紋覆蓋來自在後的側面的側面與尾部鰓蓋到尾鰭基底活著時; 這一條條紋過度地而且使在保存的標本中是顯著的深的橫臥側面中央的斑紋陰暗; 上面與下面側面中央的條紋身體是銀白色.(參考文獻 59215) 很多的黑色素細胞在頭部與鰓蓋上出現, 而且側面的鱗片邊緣的周圍散佈在身體有集中。 (參考文獻 59215) 背鰭與胸鰭是暗色的灰色; 脂鰭是白灰色具有一個深色的末梢部的邊緣; 尾鰭是暗色的灰色，而且中間地每支鰭叉子是深的深紅色的紅色; 臀鰭的前面而末梢部邊緣是白色的, 然而其餘的鰭是墨黑色; 腹鰭是白色的。 (參考文獻 59215)
